A vehicle poses a unique listening environment. Speaker distances vary
widely to each listening position. These special conditions can
be
overcome using the included microphone and the powerful
measurement system in this processor. The processor measures and
analyzes data automatically to optimize time correction for each speaker
and listening position selected.

in
a quiet location.
• Close doors, windows, sunroof, etc.
